This invention relates to road machines, and more particularly to a road machine designed for reconditioning road surfaces.

The primary object of the invention is to provide `a machine of this character which may be moved along over a road surface, the machine being provided with means for looseningthe road surface, and lmeans for conveying the loose material rto the center of the road to recrown the road.

Another object of the inventonis to pro-1` vide means for adjusting the machine vertically with respect to the road surface, there,-

by regulating the depthof operation ofthe blades `or spikes that. act to loosen the` road g surface.

With the foregoingiandV other objects inv view, whichwill appear as the description proceeds, the invention resides inthe com-rv bination and arrangement of parts and 1nthe details of construction hereinafter described andl claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made departingV from thel spirit of the invention. y Referring to the drawings:

Figure 1 is a plan View of a road machine constructed in accordance with the invention.

Figure 2 is a side elevational view thereof. Referring to the drawings in detail, the road machine embodies a frame including side bars 5 and front and rear bars 6 and 7 respectively, the side bars being connected to the front and rear bars at the ends thereof.y y

Mounted on the side bars 5 at points adjaf cent to the forward end thereof, are bearing members 8 that accommodate the shaft 9 on which the spikes 10. are mounted, the shaft being shown as provided with reduced end portionsthat fit inthe bearings.

Mounted on one end of the shaft 9, is a i sprocket 11 over whichfthe chain 12 operates,

, the chain 12 also operating over a sprocket rotated by the/tractor or machine used in dragging the machine over the road surface. As clearly shown by Figure 1 of the draw* ings, one end kof the shaft 9 extends an apwithin the scope of what is claimed, withoutA Y' bladesA 24.L f

padane aisance beyond desde bar- 5 a yone'side 'of'theframa where it'z is mounted -injthevlbearing 13 secured to the auxiliary ."frame`14 thaty extends'beyond one side of the frame ofthe machine. Operating ad" acentV to the vshaft 9, is a bearingslG, theshaft 15. supporting the pinf ion 17l that"V meshes rwith the pinion 18 mounted on the reduced end of the shaft 9,

so that movement of the shafty 9 is transmitted to the shaft 15. A beveled .pinion 19 is' also mountedron the shaft 15 and is in mesh with the beveled pinion 20 mounted on one end of the shaft 21 that is mounted in bearings 22 and 23 respectively. Thusit will be seen that rotar movement of the shaft 15 is imparted to tfi the shaft.

Blades 24 are are arranged helically around the shaft 21,

securedto the shaft 2l and` so that as the shaft 21 risr'rotated, material willy be fed inwardly from the outer edge Y of theroad surfacev over which the machine is moving, toa point adjacent to the crown of the road'.l Owing to the `fact'that the e shaft 21 to rotate shaft 21 is arranged at an oblique angle with l respect-to the side bars 5, it will be seen thatV the blades24 secured to the shaft'will ha'vefl a further tendency to vpush thefmaterial inwardly. l

At.. the rear of the machine, is a bar 25 that has its ends mounted in bearings 26, the 1 i. bar 25 providing a Vsupport for the arms 27 y formed with openings to receive the shaft of the roller 28 that rolls over the loosened road surface to pack the road surface.

one end lof the roller, is an arm 29 to which the link 30 is connected, the'opposite 'end of ythe link having'connection with the lever 31 'that is operatedV by the attendant to raise and lowery the roller 28 to adjust the frame of the machine vertically regulating the depth ofvoperation of the. spikesr lOand It might be further stated'that the spikes 10 are arranged helically Vof the shaft 9 so that the diggingv operationv ofthev spikes will be continuous. jLinks 32 are provided at Extending 4upwardly fromthe arm 27 at' I the front end of the machine and provide means for connecting the machine yto a tractor or similar device whereby the device ma be pulled along over the ground surface. chain 33 has connection With the machine and is adapted to be hooked over the hook 34 to regulate the depth of operation of the spikes and blades.

I claim: f In a road machine, a frame, a shaft disposed transversely. of the frame, spikes arranged helically on the shaft, a shaft disposed diagonally across the frame, oneend of the diagonal shaft being disposed near v one end of the first mentioned shaft, gearing for transmitting movement of the rst mentioned shaft to the later shaft, blades arranged helically around the last mentioned shaft, and means for transmitting movement to the first mentioned shaft.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature.
